Recently, the "fish disease hotline 110" of the Fisheries Bureau of Yingshang County in Anhui Province has received a series of telephone calls from farmers, which shows that many grass carp and fish do not eat and have sporadic deaths. In order to fully understand the condition of the disease, avoid the spread of immune diseases, and minimize the losses caused by the farmers due to diseases, the county bureau immediately organized five aquatic technicians to carry the testing instruments to Balihe Fisheries and Caigang Xinhong Aquaculture Cooperative, etc. In-depth development of Tangkou "fish disease experts Tangkou consultation", and effectively solve problems for the majority of farmers. After the technician arrived at the site, he carefully asked the details of the occurrence of grass carp in each pond, and then conducted on-site testing of fish and water samples in the pond. After a comprehensive analysis of various factors, the preliminary determination of the disease is grass carp liver and gall syndrome. The reason for this is that as the water temperature continues to increase, the fish eat well, and inputs such as feed are used frequently. Because the pool water was not updated in time, improper use of aerators resulted in over-fertilization of the pool water, low dissolved oxygen in the water, excessive levels of harmful substances such as ammonia nitrogen, hydrogen sulfide, and nitrite, and deterioration of the water quality, causing grass carp liver and gall syndrome. Finally, technical personnel gave guidance on the treatment of the disease: First, immediately stop feeding for 2 days to 3 days; second, timely update of pool water; 3, Quanchiposa EM bacteria and other water quality improver to improve water quality; Fourth, after 3 days Liver and vitamins are mixed with bait. At the same time, it is emphasized that farmers need to develop good breeding habits, scientific feeding, scientific drug use, rational use of aerators, and maintaining good water quality.
